Beaver evolution or creation?

The beaver is one of the most common animals in North America and Eurasia and is known for its small, furry body, and for its most distinguishable feature, its tail that resembles a paddle. The beaver also has webbed back feet like a duck that aids in swimming, however the beaver is a mammal. How can a mammal have webbed rear feet like a duck and a tail that looks like a paddle while its front legs have loose toes? In addition to its unique body features, beavers are also known for their ability to build structures such as dams, canals, and lodge homes. Beavers build dams in creeks to protect against predators and to obtain easier access to food in the winter. Beavers build homes or lodges from tree branches and mud that freezes in the winter, thereby creating a hard structure to live inside that provides protection for the beaver. The lodge is cleverly designed so that the only entrance into the lodge is from under water, and this feature prevents most other animals from entering the lodge and therefore provides protection for the beaver and its family. The lodge is constructed with the same materials as the dams and beavers begin construction of the lodge in the late summer by obtaining the materials first and constructing the lodge before the cold winter sets in. How does the beaver know when to begin to build the lodge and how does he learn how to do it? These unique behaviors along with the unique body features of the beaver are difficult for the evolutionist to explain and therefore give strong evidence for the creation model that proposes a special creation during the Creation Week 6,000 years ago for the creation of the Earth and all life on Earth.
